HA16158FP

HA16158P/FP PFC & PWM Control IC REJ03F0147-0200 Rev.2.00 Jan 30, 2007 Description The HA16158 is a power supply controller IC combining an AC-DC converter switching controller for power factor correction and an off-line power supply switching controller. The PFC (power factor correction) section employs average current mode PWM and the off-line power supply control section employs peak current mode PWM. The HA16158 allows the operating frequency to be varied with a single timing resistance, enabling it to be used for a variety of applications. The PFC operation can be turned on and off by an external control signal. Use of this on/off function makes it possible to disable PFC operation at a low line voltage, or to perform remote control operation from the transformer secondary side. The PWM controller includes a power-saving function that reduces the operating frequency to a maximum of 1/64 in the standby state, greatly decreasing switching loss. The PFC section and PWM section are each provided with a soft start control pin, enabling a soft start time to be set easily.

UVL Circuit The UVL circuit monitors the Vcc voltage and halts operation of the IC in the event of a low voltage. The voltage for detecting Vcc has a hysteresis characteristic, with 16.0 V as the start threshold and 10.0 V as the shutdown threshold. When the IC has been halted by the UVL circuit, control is performed to fix driver circuit output low and halt VREF output and the oscillator. 16.0V Vcc 10.0V 4.5V 4.5V VREF V_CT (internal signal) PWM-RESET (internal signal) PFC-DT (internal signal) PFC-RAMP (internal signal) PWM-OUT PFC-OUT Figure 1 Rev.2.00 Jan 30, 2007 page 11 of 23 HA16158P/FP 2. Soft Start Circuit (for PWM Control) This function gradually increases the pulse width of the PWM-OUT pin from a 0% duty cycle at start-up to prevent a sudden increase in the pulse width that may cause problems such as transient stress on external parts or overshoot of the secondary-side output voltage. The soft start time can easily be set with a single external capacitance. 3.2V V_PWM-SS 1.6V V_CT (internal signal) PWM-SS comp. out (internal signal) PWM-OUT Figure 2 Soft start time tss-pwm is determined by PWM-SS pin connection capacitance Css-pwm and an internal constant, and can be estimated using the equation shown below. Soft start time tss-pwm is the time until the PWM-SS pin voltage reaches upper-end voltage 3.2 V of the IC-internal CT voltage waveform after VREF starts up following UVLO release. Soft start time tss-pwm when Css-pwm is 3.3 nF is given by the following equation. tss-pwm = 33 [nF] × 3.2 [V] Css-pwm × Vct-H = 25 [µA] Iss-pwm ≈ 4.2 [ms] * Iss-pwm: PWM-SS pin source current, 25 µA typ.

Soft Start Circuit (for PFC Control) This function gradually increases the pulse width of the PFC-OUT pin from a 0% duty cycle at start-up to prevent a sudden increase in the pulse width that may cause problems such as transient stress on external parts or overshoot of the PFC output voltage (B+ voltage).

PFC On/Off Function On/off control of the PFC function can be performed using the PFC-ON pin. If an AC voltage that has undergone primary rectification and has been divided by an external resistance is input, it is possible to halt PFC operation in the event of a low input voltage. On/off control is also possible by using a logic signal. When the PFC function is turned on/off by using the PFC-ON pin, however, the PFC-SS pin cannot be reset. Therefore, a soft start is not operated at the start-up by the PFC-ON pin. The figure below illustrates an example of circuit for simultaneous reset of the PFC-SS pin and PWM-SS pin. VREF PFC-SS PWM-SS PFC-ON ON/OFF signal Figure 4 Example of Circuit Configuration to Turn On/Off PFC & PWM Functions This IC also incorporates a function that automatically detects a 100 V system or 200 V system AC voltage at the PFCON pin, and switches multiplier gain and the PFC-CS comparison voltage. These functions simplify the design of a power supply compatible with worldwide input.

Power Saving in Standby State (for PWM Control) When the output load is light, as in the standby state, the operating frequency of the PWM control section is automatically decreased in order to reduce switching loss. Standby detection is performed by monitoring the PWM-COMP voltage, and the operating frequency is decreased to a maximum of 1/64 of the reference frequency determined by an external timing resistance. As standby detection is performed on a reference frequency pulse-by-pulse basis, the frequency varies gently according to the output load.

Overvoltage Latch Protection (for PWM Control) This is a protection function that halts PWM-OUT and PFC-OUT if the secondary-side PWM output voltage is abnormally high. Overvoltage signal input is shared with the PWM-SS pin. When this pin is pulled up to 4.0 V or higher, the control circuit identifies an overvoltage error and halts PWM-OUT and PFC-OUT. The power supply is turned off, and the latch is released when the VCC voltage falls to 7.1 V or below.

Operating Frequency The operating frequency is adjusted by timing resinstance RT. Adjustment examples are shown in the graph below. The operating frequency fpwm in the PWM section is determined by the RT. The operating frequency fpfc in the PFC section is half the value of fpwm. The operating frequency in the PWM section can be estimated using the approximate equation shown below. RT = 200 kΩ: fpwm ≈ fpfc = 2.60 × 1010 = 130 [kHz] RT fpwm = 65 [kHz] 2 This is only an approximate equation, and the higher the frequency, the greater will be the degree of error of the approximate equation due to the effects of the delay time in the internal circuit, etc. When the operating frequency is adjusted, it is essential to confirm operation using the actual system. 1000 fpwm, fpfc (kHz) 100 fpwm fpfc 10 10 100 RT (kΩ) 1000 Figure 8 Rev.2.00 Jan 30, 2007 page 18 of 23 HA16158P/FP Characteristic Curves Power Supply Current vs. Power Supply Voltage Characteristics 10.0 Ta = 25°C 8.0 Icc (mA) 6.0 4.0 2.0 0.0 8.0 10.0 12.0 Vcc (V) 14.0 16.0 18.0 Standby Current vs. Power Supply Voltage Characteristics 1.0 Ta = 25°C 0.8 Icc (mA) 0.6 0.4 0.2 0.0 0.0 2.0 4.0 6.0 8.0 10.0 12.0 14.0 16.0 18.0 Vcc (V) Rev.2.00 Jan 30, 2007 page 19 of 23 HA16158P/FP VREF Output Voltage vs. Ambient Temperature Characteristics 5.20 5.15 5.10 VREF (V) Iref = 1mA 5.05 5.00 4.95 4.90 4.85 4.80 −50 −25 0 25 50 75 100 125 Ta (°C) Operating Frequency vs. Ambient Temperature Characteristics 160 RT = 200kΩ 140 Frequency (kHz) fpwm 120 100 80 fpfc 60 40 −50 −25 0 25 50 75 100 125 Ta (°C) Rev.2.00 Jan 30, 2007 page 20 of 23 HA16158P/FP UVL Start-up Voltage vs. Ambient Temperature Characteristics 20.0 19.0 18.0 17.0 VH (V) 16.0 15.0 14.0 13.0 12.0 −50 −25 0 25 Ta (°C) 50 75 100 125 UVL Shutdown Voltage vs. Ambient Temperature Characteristics 14.0 13.0 12.0 11.0 VL (V) 10.0 9.0 8.0 7.0 6.0 −50 −25 0 25 Ta (°C) 50 75 100 125 Rev.2.00 Jan 30, 2007 page 21 of 23 HA16158P/FP Application Circuit Example 1.5mH Rec+ T1 Q1 B+ OUT 51k(5W) (385V dc) To PFC-FB from auxiliary 500k VRB1 Rec− From PFC-OUT + 330µ (450V) 20V + 56µ 3.3k GND VCC OSCILLATOR 3.2V 7.7µs 200k 1.6V 130kHz CT 27.5V 3.85µs PWM-RES PFC-DT 3.4V 65kHz RAMP UVL H L 16V UVLO 10V VREF In GOOD Out VREF GOOD R Q H L 5V VREF Generator 0.1µ 5V Internal Bias VREF RT 770ns VREF 36k 3000p CAO 15.4µs 0.65V 270p 1.02M 750k IMO = K {IAC × (VEO − 1V)} PFC -OUT Gate Driver ±1.0A(PEAK) To Q1 gate IAC IAC VEO K PFC-CAMP IMO 3.3k − + VREF − + S −0.5V −0.25V R To main trans Q 100 0.082 (5W) PFC -CS 0.015µ 1k + − PFC-CLIMIT OCP K = 0.20 S VREF GOOD Gate Driver ±1.0A(PEAK) GAIN SELECTOR PFC -EO PWM -OUT 0.66 (1W) Q2 1M K = 0.05 R Q 2.5V S 0.68µ 0.47µ 1M VREF 3.80V 3.40V PFC -FB + − From VRB1(B+monitor1) − + − + PWM -COMP 1V R 2R 1.4V 1000p 240 200 720k + − 2.80V 2.60V PFC-OVP Power Saving for PWM f/64 Divider PWM-RES − + 1.7V PWM -CS 2200p 620 − + 20k B+ LOW PWM stop 4.4µ 18.6k PFC -ON 1200p 1.5V 1.2V 0.1µ − + 2.40V 1.50V PFC stop PFC-OFF QS R − + Vref VCC 7.1V Vref 25µA 25µA + − 4.0V VREF 0.47µ VREF OVP Latch VREF GOOD + − S Q GND Circuit Ground OCP R SOFT START − + RAMP PFC -SS 3.5V 2.5k SUPERVISOR CT PWM -SS 0.033µ Unit R: Ω C: F Rev.2.00 Jan 30, 2007 page 22 of 23 HA16158P/FP Package Dimensions 19.20 20.00 Max 16 9 As of January, 2003 Unit: mm 1 1.3 1.11 Max 8 7.40 Max 6.30 0.51 Min 2.54 Min 5.06 Max 7.62 2.54 ± 0.25 0.48 ± 0.10 0.25 – 0.05 0 ° – 15 ° Package Code JEDEC JEITA Mass (reference value) + 0.13 DP-16 Conforms Conforms 1.07 g JEITA Package Code P-SOP16-5.5x10.06-1.27 RENESAS Code PRSP0016DH-A Previous Code FP-16DA MASS[Typ.] 0.24g *1 D F 9 16 bp b1 HE NOTE) 1.
