LA5677M

Ordering number : EN3660B Monolithic Linear IC LA5677M Dual Switching Regulator Control IC Overview The LA5677M supports single-input control of the outputs of two converters of arbitrary types, including step up, step down and inverting. Since the LA5677M supports low voltage (3.6 to 18 V) and high frequency (1 to 500 kHz) operation, it is ideal for use in power supplies in battery powered portable equipment. Package Dimensions unit: mm 3035A-MFP16 [LA5677M] Features Operates at low voltages (3.6 to 18 V) Can be used with high frequency oscillators (1 to 500 kHz) Built-in low input malfunction prevention circuit Built-in timer-latch short circuit protection circuit Specifications Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Error amplifier input voltage Collector output voltage Collector output current Allowable power dissipation Operating temperature Storage temperature Symbol VCC max VI VO IO Pd max Topr Tstg Operating Conditions at Ta = 25°C Conditions Parameter Recommended supply voltage Error amplifier input voltage Collector output voltage Collector output current Feedback pin current Feedback resistance Timing capacitance Timing resistance Oscillator frequency Symbol VCC VI VO IO IFT RNF CT RT fOSC Conditions min 3.6 1.05 –0.3 100 150 5.1 1 SANYO: MFP16 Ratings 20 20 20 21 330 –20 to +85 –40 to +125 Unit V V V mA mW °C °C Ratings typ max 18 1.45 +18 20 45 15000 100 500 Unit V V V mA µA kΩ pF kΩ kHz Any and all SANYO product...
