MP9218DGT-LF-Z

MP9218 High Performance Regulated Charge Pump DESCRIPTION FEATURES The MP9218 is a high performance, regulated charge pump converter. Its input voltage ranges from 2.8V to Vout. The output voltage is regulated to a fixed 5V. No external inductor is required for simplicity and compactness. Internal soft-start circuit effectively reduces the in-rush current both while start-up and mode change.           The MP9218 is available in a compact TQFN-6 (2mmx2mm) package Input Voltage Range: 2.8V to 5V Internal Soft-Start Output Maximum Current up to 110mA Fixed 5V Output Voltage with 30mV Ripple 2X Charge Pump Fixed 1.35MHz Switching Frequency Over Current Protection Short Circuit Protection In-rush Current limit TQFN-6 (2mmx2mm) package and Lead (pb)-Free APPLICATIONS     Cell phone, Smart phone PDA or hand Held Computer LCD Display Supply TV-Remote Control All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.

The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD (MAX) = (TJ (MAX)-TA)/θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7, 4-layer PCB. www.MonolithicPower.com MPS Proprietary Information.

All Rights Reserved. 6 MP9218–HIGH PERFORMANCE REGULATED CHARGE PUMP OPERATION CP CN IN OUT EN GND Figure 1— Functional Block Diagram The MP9218 uses a switched capacitor charge pump to boost an input voltage to a regulated output voltage. Regulation is achieved by sensing the charge pump output voltage through an internal resistor divider network. A switched doubling circuit is enabled when the divided output drops below a preset trip point controlled by an internal comparator. The switching signal, which drives the charge pump, is created by an integrated oscillator within the control circuit block. The fixed charge pump switching frequency is approximately 1.35MHz. MP9218 Rev. 1.01 8/23/2017 The MP9218 has complete output short-circuit and thermal protection to safeguard the device under extreme operating conditions. An internal thermal protection circuit senses die temperature and will shut down the device if the internal junction temperature exceeds approximately 145°C. The charge pump will remain disabled until the fault condition is relieved. www.MonolithicPower.com MPS Proprietary Information. Patent Protected.
