Features - - - .. - - - - - - 2.3 to 5.5V Input Voltage Range Adjustable Frequency: Maximum 1MHZ Incorporates Soft-start Function Built-in Short-circuit Detection Circuit (SCP) Low Operating Current: Maximum to 1m A Low Shutdown Current: Maximum to 1m A Package: MSOP-8, TSSOP-8 Under Voltage Lockout Lead Free Available (Ro HS pliant) General Description The A PW 7078 is a single P W M, s tep-up DC-DC c ont roller wit h low operating volt age applic at ion int egr at ing s oft-st art and short circ uit detect ion function. And the oscillator switching frequency on chip can be operated by terminating OSC pin to connect c apac itor and resis t or for adjus t able operating frequency. Soft-start is adjusted with external capacitor, whic h s et s t he input current ramp. Bes ides, the external pensation FB pin will apply the flexibility in the dynamic loop status, which allow using small, low equivalent series res istance (ES R) c eramic output capacitors.
